The accumulation of plaque inside the arteries can be an insidious condition with grave consequences that include blood clots and strokes, but luckily it does give off some tell-tale signs. Researchers in the UK have developed a new type of glowing probe that focuses on one of them, increasing its fluorescence in the presence of a key enzyme and possibly acting as an early warning sign for cardiovascular disease.
We know exercise is a good thing. It improves everything from cardiovascular disease to one’s cognitive health. Observational studies have also seen physical activity lessen age-related vision loss, but until now it hasn’t been clear how causal that relationship has been. New research from the University of Virginia (UVA) is offering the first experimental evidence to show how exercise can directly slow, or even prevent, macular degeneration.
